摘要:
Dual-optical module autofocus (AF) or AF plus optical image stabilization (OIS) cameras with reduced footprint and reduced mutual magnetic interference. Some AF+OIS cameras may include a single AF actuation assembly that moves two lens barrels in unison. Some AF cameras or AF+OIS cameras may have two AF actuation sub-assemblies and associated magnets for independent AF operation of each lens barrel, the magnets shared in a manner that cancels magnetic influences of one AF actuation sub-assembly on the other AF actuation sub-assembly, thereby allowing the two lens barrels to be positioned in close proximity, saving parts and fabrication costs.

An image capture lens is equipped with: a diaphragm which is formed on a substrate, adjusts a light quantity, and has a predetermined aperture; an inorganic or organic adhesion layer formed on the substrate such that the diaphragm is exposed; and a resin part which has a lens part made from a curable resin. The resin part is directly jointed to the inorganic or organic adhesion layer and diaphragm. The surfaces of the substrate on which the diaphragm is formed is subjected to a modification treatment so that a water contact angle is within a range of 3° to 30°.

A variety of optical arrangements and methods of modifying or enhancing the optical characteristics and functionality of these optical arrangements are provided. The optical arrangements being specifically designed to operate with camera arrays that incorporate an imaging device that is formed of a plurality of imagers that each include a plurality of pixels. The plurality of imagers include a first imager having a first imaging characteristics and a second imager having a second imaging characteristics. The images generated by the plurality of imagers are processed to obtain an enhanced image compared to images captured by the imagers.
